Optoma Projector DX605 - Screen goes black after about 30 sec to a minute of operating. I'm wondering if there is a filter I should be cleaning, because it seems as though it's an overheating issue.

SOURCE: The optoma hd72 projector lamp

I had this exact same problem. I have changed bulbs gotten 1000 or so hours from new bulb, changed the lamp driver and gotten about 600 more hours from new lamp driver. New lamp cost me $350, lamp driver cost me $120. Then I read on a page to try and flip it right side up, because I had it ceiling mounted upside down. I flipped it right side up and it works perfectly and has been working perfectly for 2 months now. I know it sounds stupid, but it actually worked for me, and it costs you nothing to try it. For some reason, gravity effects this unit.

Possible cause is overheating.
Do you hear the fan working?
What happens when you use the lowest level light output?
Does it run longer?

Also possible cause is a faulty temp sensor.
AC wire connection may not be firmly pressed in socket.

When turning on the projector it shows the Optoma logo but will not boot to the home screen. Is there a way to reload the home screen software?


Depends on the model. If you saw a little fan, then there is a fan problem. There might be 3 fans. 2 square ones and one blower fan. Look for plugs with 3 wires(red/white/black or red/yellow/black). Those will lead to the fans from the mainboard. Occasionally the fan will spin but the tachometer lead will stop reporting the fan status and the projector shuts down. To being with I would clean out the projector fans and ducts thoroughly. That may clear up the issue. Otherwise there is a button press sequence to enable the service menu, but you cannot upload new firmware without special optoma software that isnt available. Another possibility is you have failing filter capacitors in the power supply. Be careful poking around under the hood. There is lethal high voltage possibly stored even when unplugged.

Need power supply unit


Optoma fixes all their own equipment. They have no dealers as far as I know...
This place says they can fix it. They may have parts. Offices in California and Georgia.

ALSO CHECK YOUR FAN. IF THE FAN OR A HEAT SINK IS NOT WORKING PROPERLY (I.E. THE FAN MAY JUST NEED TO BE CLEANED OR REPLACED, THERE SHOULD BE A SMALL HEAT SINK. IF CLOUDED W/DUST, IT WILL KEEP THE OPERATION SHORT). ALSO CHECK IF YOU HAVE SET ANY TEMPERATURE SHUTDOWN PARAMETERS. IF YOUR LAMP HEATS UP FOR SO LONG AND REACHES A TEMPERATURE THAT WILL AFFECT THE CIRCUITS, THIS OF COURSE WILL SHUT DOWN YOUR UNIT UNEXPECTEDLY. HOPE THIS HELPS...JGUAM
